ATTACHMENT FOB HEADLIGI-ITS.

Specification of Letters Patent.

Patented Apr. 12, 1910.

Application filed June 24, 1909. Serial No. 504,121.

To all whom it may concern:

Be it known that I, FREDERIC J. PFISTER, a citizen of the United States,residing at San Francisco, in the county of San Francisco and State ofCalifornia, have invented a new and useful Attachment for Headlights, ofwhich the following is a specification.

The objects of the invention are, generally, the provision in amerchantable form, a device of the class above mentioned which shall beinexpensive to manufacture, facile in operation and devoid ofcomplicated parts; specifically the provision of clips of novel andimproved construction, adapted to be mounted upon the side walls of aheadlight; the provision of a sign provided with elements adapted to beengaged by said clips; other and further objects being made manifesthereinafter as the description of the invention progresses.

The invention consists in the novel construction and arrangement ofparts hereinafter described, delineated in the accompanying drawings andparticularly pointed out in that portion of this instrument whereinpatentable novelty is claimed for certain distinctive and peculiarfeatures of the device, it being understood, that, within the scope ofwhat hereinafter thus is claimed, divers changes in the form,proportions, size, and minor details of the structure, may be made,without departing from the spirit or sacrificing any of the advantagesof the invention.

Similar numerals of reference are employed to denote corresponding partsthroughout the several figures of the drawings.

In the accompanying drawings, Figure 1 shows my invention in verticaltransverse section looking toward the front of the headlight; Fig. 2 isa horizontal section, parts being broken away; Fig. 3 is a sideelevation of one of the clips; Fig. 4 is a detail perspective designedto show the cooperation between the sign and the clip, parts beingbroken away.

The improved device forming the subject matter of this application forLetters Patent is adapted to be mounted in headlights,

signal lanterns and the like, to retain therein, a sign carrying uponits face a distinguishing characteristic.

The supporting member in which my device is mounted may be a lantern orheadlight of any form. In the accompanying drawings, I have shown alantern and denoted the same by the numeral 1. The lantern is shownmerely to illustrate one form of the device with which my invention maybe assembled, and a detailed description of the lantern is notnecessary, it being understood that the lantern may be of any form, andthat my invention may be assembled therewith in any manner dictated bythe exigencies of the proposed use.

The invention comprises a pair of clips which are denoted by the numeral2 in the several figures of the drawings. These clips are adapted to beoppositely disposed upon the side walls 3 of the lantern, with whichthey may be assembled in any suitable manner, screws l passing throughthe side walls 3 of the lantern to engage the clips 2, forming theattaching means in the present instance. The adjacent faces 5 of theseclips 2 are provided with grooves 6. These superficial grooves 6terminate anteriorly with-- in the contour of the clips and at theirupper extremities, the said grooves are forwardly extended to intersectthe edges 7 of the clips. Since these clips 2 are identical inconstruction a detailed description of one of them will answer for both.

It will be seen by an examination of Figs. 3 and 4: that a portion 8 ofthe edge 7 of the clip is left intact to define the lower portion of thegroove, the upper extremity of this portion 8 being provided with a lip11 arranged to extend into the groove 6 intermediate the ends thereof,to overhang the lower portion of the groove. The upper portion of therear face of the part 8 which defines the forward face of the groove 6is rearwardly inclined as denoted by the numeral 9, the lower portion ofthe rear face of the member 8 being disposed in upright relation asdenoted by the numeral 20 in Fig. 3. The bottom of the groove 6 isupwardly inclined toward the edge 7 of the device as denoted by thenumeral 10. The

rear wall 12 of the groove is reversely curved to diminish the groove atits lower end, the said reversely curved portion terminating ultimatelyat its lower end, in a straight, upright portion 14, disposed parallelto the portion 20 of the forward face of the groove.

The display element which it is the func tion of the clip to hold, mayinclude a sign 15, preferably fashioned from thin metal and carryingstenciled characters. This sign 15 is terminally provided with elementsadapted to be inserted into the clips 2 to be retained in the grooves 6therein, and these elements in the present instance are shown in theform of the terminal parts of a rod 16 which is rigidly assembled in anysuitable manner, with the upper edge of the sign 15. The ends of the rod16 are adapted to fit somewhat closely between the portions 14 and 20 ofthe groove, the lower edge of the rod 16 being beveled as denoted by thenu meral 17, to conform to the upward inclination of the bottom 10 ofthe groove. upper portions of the forward faces of the rod 16, adjacentthe ends thereof, are cut away as denoted by the numeral 18, to conformto the rearward inclination 9 of the forward face of the groove, and thewidth of the rod 16 is such that, as shown in Fig. 3, when the rod ismounted in place in the clip, a slight space 19 will intervene betweenthe upper edge of the rod and the lower face of the overhanging lip 11,beneath which the rod is positioned when the device is assem bled.

In practical operation, the extremities of the rod 16 are introducedinto the portions of the groove 6 which intersect the edges 7 of theclips 2. The rod 16 is then pushed rearward, resting upon the lips 11,to the rear of which the extremities of the rod 16 will drop. Theextremities of the rod will then traverse the reversely curved rearwalls 12 of the groove, and ultimately enter the space between theportions la and 20 of the groove, the beveled portion 17 of the rodresting upon the upwardly inclined portion 10 of the groove, thecut-away portion 18 of the forward faces of the ends of the rod bearingagainst the rearwardly inclined portion 9 of the front wall of thegroove. The peculiar configuration given to the groove in those portionsthereof which lie beneath the lip 11, tend to hold the rod 16 firmly inplace within the clips 2, and to prevent the sign 15 from swinging oraltering its position.

By inclining the sign 15 or the rod 16, the sign may readily be removedfrom the clips 2, the space 19 permitting the extremities of the rod tobe raised slightly, so that the same may be tilted back for removal fromthe clips in which it is mounted.

The
